Explanation
Ramp meters are signal lights used to control the flow of vehicles entering a freeway. They are typically located about halfway down the entry ramp. Like traffic signals at intersections, drivers must wait for the light to turn green before proceeding. Only one vehicle is allowed to enter the freeway each time the light turns green, and it is illegal to drive through a red light. Ramp meters help reduce traffic congestion and make merging smoother and safer. If the ramp meter is dark, you may proceed without stopping and merge or yield as traffic conditions allow.
